A compact car, mass 875 kg, moving south at 16 m/s, is struck by a full-sized car, mass 1660 kg, moving east at 12 m/s. The two cars stick together, and momentum is conserved in the collision. The wreck skids along the ground and comes to a stop. The coefficient of kinetic ...

Suppose you have a meter stick with two masses attached. The mass m1 is 0.60 kg and it is located at x1 = 30 cm from the left (zero) end of the meter stick. The pivot point is located at x = 45 cm. The mass of the meter stick (mms = 0.40 kg) is located at its geometric center...

Hung vertically, a mass less spring extends by 3.00 cm a mass of 739. G is attached to its lower end. The same mass and spring are then placed apart on a table. The spring is fixed in place and then the mass is given a velocity of 0.900 m/s towards the spring. a) What is the ...
